5.3.2 Card-sized I/O Specifications
The card-sized I/O (HR361/HR371) specifications are shown below. The card-sized I/O has 16 input
points and 16 output points per card. When the card-sized I/O connector PCB is connected to RIO1, up
to six cards can be used, and when connected to RIO2 and RIO3, up to eight cards can be used. The
power supply (+24V, +5V) must be supplied from an external source.

(2) Setting the channel No.
The card-sized I/O does not have a rotary switch, etc., for setting the channel No. Connect the
connector CF30 SEL1 to 3 signal pin to +5V or GND on the base PCB as shown below. The
card-sized I/O occupies one channel. Refer to section 6.14 Setting of channel No. when using
multiple remote I/O units for the occupied channels.

(3) External power supply specifications
The power supply (+24V, +5V) for the card-sized I/O must be supplied from an external source.
Prepare a power supply (stabilized power) that satisfies the following conditions per card.

+24V ±5%
Output voltage
+5V ±5%
Ripple/noise 240mVp-p Ripple/noise 50mVp-p
Output current 1A Output current 0.4A
The output current is the value when
60mA x 16 points are used. Prepare a
power supply that satisfies the total
output current of the +24V output.
